研究京西(燕山西段及北京西山地区)区域地质构造及其演化对煤层的赋存控制作用,对揭示京西煤矿矿井动力灾害发生的动力学背景具有重要意义.从京西煤田内矿井动力灾害发生的区域构造背景入手,结合构造应力场分布特征,利用地质动力区划构造凹地反差强度评价方法,对具备发生动力灾害条件的矿井给出量化评价指标.通过分析确定,京西煤田开采矿井具备发生矿井动力灾害的动力环境,这对指导矿井安全开采具有现实意义.

In the early middle Jurassic, Jurassic basin in west Beijing entered the important coal-forming period. It shaped current tectonic patterns during middle and late Yanshan tectonic movement. The study of controlling action on coal seam occurrence by regional tectonic and its evolution has great importance for revealing the dynamic background of mine dynamic disasters in west Beijing. The paper, based on the regional tectonic background for mine dynamic disasters in west Beijing coalfield, combined with tectonic stress field distribution characteristics, using geological dynamic division hollow contrast strength evaluation methodology, gave quantitative evaluation indexes to the mines which have hydraulic disaster condition. By the analysis, it was identified that there exist dy-namic environments for dynamic disasters in coal mines in west Beijing coalfield, which has realistic significance for guiding safe mining.
